If your car isn’t new enough to have Bluetooth integration, this Steering Wheel Bluetooth Adapter may be the perfect solution. It fits around the inner part of a steering wheel with some options for size adjustment. For $63 the adapter sports a microphone and speakers for speakerphone, an LCD display for incoming callers, SD port for MP3s, USB and FM-out so you can play everything back through your car’s stereo.
There is a catch however, the adapter’s power source is your car’s cigarette lighter. You would be connecting your steering wheel to the lighter. Which could be a safety hazard. Unless it’s rechargeable. In that case don’t charge it while driving.
